, To all whom it may concern 3 Be it known thatII, CLARENCE. Si ZINK, acitizen of the-- United States, residing. at Marshall, in the county ofSaline and State of Missouri, have invented certain new and usefulImprovements inDevices for Testing Working of Magnetos, &c.; and I dohereby declare the following to'be a full, clear. and exact descriptionof the invention, such as will enable-others skilled in the art towhichit appertains' to make and use the same, reference' being had tothe accompanying drawings, and to the letters and figures ofreferencemarked thereon, which form a part of this specification. Thisinvention relates to new and useful improvements in indicators adaptedto show the working of a magneto andcoil at a glance to determine as towhether or not the sparking is working properly.

The invention consists of various details of construction, combinationsandarrangements of parts which will be hereinafter fully described,shown. in the accompanying drawings and then specifically defined in theappended claim.
